Overview
The SFH610A-1X018T is a high-reliability optocoupler featuring an infrared LED and an NPN phototransistor output. It provides electrical isolation with a rated insulation voltage of 5300 Vrms. The device utilizes a surface-mount package configuration, specifically identified as 4-SMD in distributor documentation. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum collector current of 50 mA, and a power dissipation rating of 100 mW. The component supports a maximum forward current of 60 mA with a typical forward voltage of 1.6 V.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Features a fast switching response suitable for signal transmission
- Constructed with an NPN phototransistor output stage
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission across isolated ground potentials
- Power supply feedback loops
Procurement Notes
Verify the specific suffix X018T against official Vishay datasheets to confirm the surface-mount package type, as generic SFH610A listings often refer to through-hole DIP variants. Ensure the procurement specification matches the required CTR bin and isolation voltage ratings documented in the manufacturer's release notes.
Selection Notes
Select this component when a surface-mount form factor is required for high-isolation applications. Compare the 5300 Vrms insulation rating against system safety requirements. Verify that the 50 mA collector current limit meets the load drive requirements of the downstream circuitry.
Part Context
This part belongs to the SFH610A series of transistor-output optocouplers manufactured by Vishay Semiconductor Opto Division. The series is characterized by high reliability and robust isolation capabilities. The specific model denotes a surface-mount variant, distinct from the standard through-hole PDIP versions found in the same family.
Replacement Considerations
Official cross-reference data indicates VO610A-1 as a recommended alternative within the Vishay portfolio. Verify pinout compatibility and CTR specifications before substitution.
